I think that Allah himself before his attendants tell some funny story or give the next lecture, too, at first lit up, slowly drags on and think.
The plane before take off, long roars, then he was being taken across the entire airfield on the runway, then it is even more noise, then scattered, and only by doing it all up in the air.
Helicopters do not have to run up, but he kept noise, rattles, shakes a fine, tense trembling before getting off the ground.
